Maybe I'm wrong about the location of resources, but didn't the Amazons report copper on their other spoke as well? If so I'd expect that the northern and southern spokes don't have copper but the other 4 do. In which case it's possible that the Mavericks have a copper city on Comet.
I had the impression it was a pattern like:
.h
c.c
h.h
.c
What you're describing seems to be:
.h
c.c
c.c
.h
That seems asymmetric, in that the middle teams ('middle' in a north-south sense) get two coppers rather than a copper and a horse. My impression was that the mapmaker was going for rotational symmetry as much as possible, rather than the kind of reflectional symmetry of what you describe.
Also wouldn't it be better if Vega moved 1S to spawn bust? It will cover more land tiles than the current location and would allow it to return to Arcturus just as quickly if it needed to. The downside is that the tile 4E of Arcturus would not be spawn busted, but that's small compared to the number of additional tiles we'd bust in the south if we moved.
"Vesta" you mean not "Vega".
I think I agree with this actually. He'll get some visibility across the lake as well, which seems like a good thing to me. We might even spot "copper city".
